HULLING=MACHINE SPECIFICATION formingpart oi Letters Patent No. 695,120, dated March 11, 1902-. Application filed February 20,1900. Serial No. 5,904. (No model.)

To atZZ whom it may concern:

Be it known that 1, JAMES EWING SANDERS, a citizen of the United States of America, residing at Dalton, in the county of Whitfield and State of Georgia, have in vented a new and useful Improvement in Hulling-lllachines, of which the following is a specification.

Thisinvention relates to hulling-machines, and more particularly to that class employed for hulling and shelling peas, beans, and the ike.

The object of the invention is to present a simply-constructed, thoroughly-efficient, durable, and portable hulling-machine which shall be thoroughly efficient in effecting the hulling of peas, beans, and the like and the separation thereof from the pods and chaff or halm and which may be readily operated manually with the output of but a small amount of energy.

With these and other objects in view, as will appear as the nature of the invention'is better understood, the same consists in the novel construction and combination of parts of a hulling-machiue, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like numerals of reference indicate corresponding parts, there is illustrated a form of embodiment of the invention capable of carrying the same into effect, it being understood that the invention therein exhibited may be varied or changed as to shape, proportion, and exact manner of assemblage without departing from the scope of the invention, and

be constructed as shown or in any other preferred manner. Supported in a horizontal position in the upper portion of the frame is a conical shell or casing 2, constructed, preferably, of sheet or plate metal and provided in its upper side at its smaller end with a feed-opening 3 and in its lower side at its larger end with a discharge-opening 4. The casing comprises an upper section 5 and a lower section 6, hinged together on one side at 7 and open at the opposite side at 8, the lower section being supported by longitudinallydisposed bars 9, suitably secured to the frame ofthe machine and serving,further,as a means of attachment for the teeth 10, which project inward from opposite sides of the drum and are arranged in staggered order, as shown in detail in Fig. 3, or in any other preferred manner, the upper section being also secured to similar bars 9 devoid of teeth, and serving to strengthen the said section against buckling or bending. Mounted upon the up per section is a hopper 11, which is coextensive in length therewith and has flared sides, as shown, and to the upper edges of the hopper above the teed-opening 3 is secured a hood 12, which operates to prevent any of the shelled peas or beans from being thrown outward from within the shell in the operation of the machine. The inclined top portion of the conical outer shell forms also the bottom of the feed-hopper, down which the material may be readily shoved to the feed-opening and into the machine, while the oppositely inclined bottom portion of the shell constitutes the chute, down which the material is urged by the aotion of the threshing-cylinder to the discharge-opening and thence through the blast to the spout. Extending through the shell and centrally thereof is a shaft 14, having its terminals journaled in suitable bearings in the frame 1, one end of the shaft havin'glmounted thereon a spur-pinion 15 and the other end a pulley 16. Secured to the shaft are two heads 17 and 18, to which are secured longitudinally-disposed bars 19, 20, 21, and 22, and secured to these bars is the threshing-cylinder 23, consisting of a sheet or plate metal jacket or body 24:, conical in shape and tapered to correspond with the shell, thereby to present an even space between the two from end to end. In addition to constituting a means of attachment for the jacket 24E the bars 19 to 22 serve as a means of attachment for the teeth 25, which are dis posed intercurrent with the teeth 10 of the shell, as shown in Fig. 4.

Projecting downward from the dischargeopening 4 is a dischargespout 26, which communicates with an upward-inclined separating-chute 27, which gradually tapers toward its discharge end 28, at which point it is constricted by an upwardly-extending curved guard 29, which operates to prevent the peas or beans from being driven out of the chute in the event that some of the same pass upwardwith the chaff or halm. A blast-fan is arranged in adrum or casing, which communicates with the lower end of the dischargechute 27, the shaft 21 of the fan carrying at one end a pulley 32, which is connected to the pulley 16 by an endless belt 33. Arranged below the discharge-chute and communicating therewith is a trough or measure 34 to receive the shelled peas or beans, and at the point where the said trough is applied the chute is horizontally offset, and above the oifset is pivoted a wing 35, which projects forwardly into the chute, the wing being pivoted to the upper portion of the fan-casing, as at 36. The wing normally occupies a horizontal position and is adjustable above and below a horizontal plane and is of such length as to prevent the threshed peas or beans from falling directly into the trough before separation therefrom of the chaff and thorough cleaning has been effected, the wing operating, further, to regulate the line of pneumatic force of the fan. Itis to be understood that the wing may be adjusted by any suitable means from the exterior of the machine, and

as this will be obvious detailed illustration is deemed unnecessary.

Journaled upon a stub-shaft 37 is a spur gear-wheel 38,the same meshing with the pinion 15 and being provided withacrank 39, by which it maybe manually rotated to actuate the threshing-cylinder, it being understood that power is transmitted from the latter to the blast-fan by pulleys 16 and 32 and the endless belt 33. I

In the operation of the machine the pea or bean vines are placedin the hopper 11, and as the material is being threshed it revolves in the shell between the latter and the threshing-cylinder, and owing to the conical form of the said parts the material works its way downward toward the discharge-opening 4, being thoroughly threshed and the peas or 'beans shelled and effectually separated from the pods before reaching said opening. As the threshed n1 aterial drops through the spout 26 into the discharge-chute 27 the blast from the fan carries away the halm, chaff, pods, and other lighter particles and thoroughly winnows the shelled peas or beans,which then. drop by gravity into the trough or measure 34:.

It will be understood from the foregoing that by means of the conical construction of the shell and threshing-cylinder not only is the passage of the material while being threshed in the machine facilitated but by disposing the hopper directly on the upper side of the shell the conical shape of the latter is utilized as a means for effecting the feeding of the material to the threshing-cylinder. By having the drum made in two sections and hinged together as described, thus to permit the upper section to be thrown back, access is readily attained to the interior of the drum to permit ready removal therefrom of any foreign substances-such as sticks, stones, or the like-which may be fed into the machine.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a hulling-machine, the combination of a two-part conical shell provided internally at each side with teeth, a toothed threshingcylinder mounted on a horizontal shaft, concentrically within said shell, a feed-hopper above and extending lengthwise of the shell, which forms the inclined hopper-bottom, a discharge-spout arranged at and receiving from the lower end of the bottom of said shell,

a receiving-spout below the discharge-spout, and a fan for passinga blast through the falling material.

EWING SANDERS.
